VALVE.

Specification of Letters Patent.

Application filed August 12, 1911. Serial No. 643,733.

To all whom it may concern:

Be it known that we, EDGAR L. Runner; and DONALD MAoKAY MACLEOD, citizens of the United States, residing at Lake Charles, in the parish of Calcasieu and State of Louisiana, have invented new and useful Improvements in Valves, of which the following is a specification.

The invention relates to valves, and more particularly to the class of throttle valves.

The primary object of the invention is the provision of a valve in which fluid supply may be controlled and shut off at will, the valve being especially useful on steam engines, pipes, gas wells, oil wells, or the like, where it is desired to use a quick acting valve.

Another object of the invention is the provision of a valve" which issimple inconstruction, thoroughly reliable and eflicient in operation, and inexpensive in manufacture.

With these and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will. be hereinafter more fully described, illustrated in the accompanying drawings, and

pointed out in the claim hereunto appended.

In the drawlngs: Figure 1 1s a side elevation of a valve constructed in accordance with the invention. Fig. 2 is a vertical longitudinal sectional view thereof. Fig. 3 is a vertical transverse section. Fig. 4 is an end elevation.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings by numerals, the valve comprises a cylindrical-shaped casing 5, the same being closed at its bottom and open at its top, the top of the said casing being formed with an outturned annular flange 6 for the detachable connection thereto of a head, presently described.

Rotatably mounted within the casing 5 is a valve body 7, the same being formed with a reduced turning stem 8 at its upper end, which is surrounded by the removable disklike head 9, the latter being secured to the flange 6 by means of a plurality of bolt members 10 passed through the head and said flange. Interposed between the head and the annular flange is a resilient gasket same being engaged by a stufling box 13, thereby preventing leakage of fluid between the stem and the said head. The reduced upper end portion forming the stem 8 provides a bearing shoulder 13, the same supporting a washer 14 which surrounds the stem 8, in turn is surrounded by the gasket- 11 and is adapted to take up wear between the valve body 7 and the said head.

Formed transversely in'the valve body, slightly to one side of its axis of movement, is a circular shaped opening 15, which latter is adapted to alternately register and close branch coupling extensions 16 projecting at right angles from the casing 5 at opposite sides thereof, the said extensions being formed with outturned annular flanges 17, towhich are adapted to be connected inlet and exhaust pipes, as usual. son of the fact that the opening 15 in the valve body 7 is located slightly to one side of its axis of movement, it provides a thickened wall at one side of the said opening, and a shallow wall at the opposite side, so that upon turning the valve body a quarter turn, the communication between the casing and the coupling extensions will be positively closed, thereby shutting oif the supply of fluid through the valve casing.

Mounted upon the upper end of the stem 8 is a turning wheel 18, the hub 19 of which is fixed thereto by means of a set screw 20, which is threaded in the hub and engages in the stem. Thus, the valve body may be turned for opening and closing the valve casing, and in operating the wheel, it is only necessary to rotate the same a quarter turn to either open or close the valve.

Suitably mounted upon the casing 5 and in communication therewith is an oil cup 21 which supplies oil to the turning valve.

What is claimed is:

A valve comprising a casing having an annular flange at the upper end thereof, a valve body rot-atably mounted in the casing and having a transverse circular opening arranged at one side of its axis of rotation, a removable head closing the upper end of the valve casing, a resllient gasket interposed between said head and said annular flange, a stem formed on the valve body and extending upwardly through said head, a washer surrounding said stem at its unct1on wlth said valve body, said washer being surrounded by said gasket, a packing gland connected with said head and sur- 7 In testimony whereof we affix our signarounding said valve stem, coupling extentures in presence of two Witnesses. sions formed at the opposite'sides of said EDGAR L.
